Australia, unfortunately, doesn’t have a release date so far…but don’t lose heart; at the very least, Shin’en have confirmed that they’re publishing the game down under.
They also updated the game’s development blog recently. The second entry details some of Jett’s inventory, such as the jet pack and vehicles. They also confirm that, in a move inspired by some of
Nintendo’s own titles, they eventually decided to
optimize the game to run at 60 FPS.
